The Kawasaki Ninja 400 breaks our hearts... here's why!

Is the new Kawasaki Ninja 400 just a Ninja 300 with an extra 100cc? Or is there more here than meets the eye? Priyadarshan Bawikar finds out.

Kawasaki Ninja 400 Road Test Review

If I had to use one word to describe the Kawasaki Ninja 400 as soon as I hopped off after my first ride on it, it would be 'shocking'!

This small(ish) capacity Ninja isn't new to shocking us... the first time it did so was when Kawasaki announced the prices in April of this year.

Now, though, it's giving us that good-kinda shock. Because, after years of getting somewhat insipid 250s and 300s, this 400 finally feels like a proper Kawasaki! And here's why...


Kawasaki Ninja 400 Road Test Review

It's got proper Ninja performance

Powering this new baby Ninja is a 399cc, liquid-cooled, parallel-twin motor that is based on the one from the Ninja 300. But, in most ways that matter, this is a new engine.

Both bore and stroke dimensions have been increased (from 62x49mm to 70x51.8mm) and the cylinders are more oversquare than before.

Even the compression ratio has been bumped up from 10.6:1 to 11.5:1.

The end result is a whopping 49PS of power coming in at 10,000rpm, which is 10PS more than the Ninja 300.

It even manages 38Nm of torque -- an increase of 11Nm over the N300.

And these power and torque figures are the highest in the segment as well.


Kawasaki Ninja 400 Road Test Review

Thanks to this performance bump, the Ninja 400 has gone on to become the quickest bike we've tested in this category, getting to 60kmph in just 2.44 seconds and 100kmph in 5.40 seconds.

It even manages great roll-on acceleration figures, managing the 30-70kmph run in third gear in 4.27 seconds and 40-80kmph in fourth gear in 4.45 seconds, of which the latter is segment-leading as well.

And at a tested top speed of 159.83kmph, this Ninja 400 is the quickest bike in this segment as well.


Kawasaki Ninja 400 Road Test Review

This motor has got real Ninja character

Don't get us wrong; the Ninja 300 is a great bike with a very likeable motor -- it's super smooth.

But it's also really peaky, which makes it quite boring in the low to mid-range.

The Ninja 400, on the other hand, not only makes more peak power and torque than this motor; it also makes it at much lower rpm as well -- 10,000rpm and 8,000rpm respectively.

And that completely changes the character of this engine compared to the 300's.


Kawasaki Ninja 400 Road Test Review

Below 4000rpm, this 400 is just as tractable and can pull from 40kmph in sixth gear without skipping a beat, which makes city riding an absolute breeze.

Get it past the 4000rpm mark though, and the motor starts to get quick and the speeds really start to climb.

In fact, at 7000rpm in sixth gear, it'll happily sit at 120kmph all day long without even a hint of vibration.

And that's great news for anyone who really plans to take this Ninja 400 touring over long distances.


Kawasaki Ninja 400 Road Test Review

Get the motor past the 8000rpm mark though, and it wakes the f*** up! The exhaust note goes into a lovely howl, and it starts to really move like a stabbed rat.

It actually gets fast enough to get you into trouble if you're not careful -- getting to the 100kmph mark in just second gear!

At this point though, the motor is far from smooth -- there is a certain gruffness that can be heard and felt, and there's a buzz in the handlebars and the footpegs too.

That said, this buzz never really gets to the point where it'll start bothering you. What it does manage to do is make the motor feel, cliched as it sounds, alive.


Kawasaki Ninja 400 Road Test Review

It handles like a Ninja should

It's not just the Ninja 400's motor that's a complete departure from the 300's. Even the chassis is completely different.

While the 300 used a diamond type frame, Kawasaki has switched to a trellis frame for this one, similar to what you see on the company's 650s.

Even the steering geometry is a lot tighter compared to the 300, with a rake and trail of 24.7 degrees and 92mm, respectively.

The wheelbase too is now a fairly short 1370mm -- 35mm shorter than the 300.


Kawasaki Ninja 400 Road Test Review

So where the 300 feels rather easy-going when it comes to handling, the 400 is super sharp.

The apt way to describe this would be 'telepathic', almost reminding us of the first generation Yamaha R15. You just think it and the Ninja 400 is willing to change direction.

It needs very little steering effort, even when you're transitioning from one corner to the next.


Kawasaki Ninja 400 Road Test Review

But don't think that just because the Ninja 400 can turn rapidly, it feels twitchy. Thanks to a long swing arm, it has inherent stability when you need it as well.

Another factor that contributes to the bike's mid-corner confidence is the fact that Kawasaki has dumped the IRC tyres that they provided with the 300 in favour of Dunlop Sportmax rubber -- 110/70 R17 at the front and 150/60 R17 at the rear.

Now we've ripped on these tyres before on larger bikes in the past, but they work really well on the 400 and provide plenty of grip, even in the rain.


Kawasaki Ninja 400 Road Test Review

So not only is this quicker in a straight line, we think its got its competition beat in handling too.

If it came down to a battle of lap times on a racetrack, this will run circles around the Ninja 300.

Heck, it'll lap faster than a Yamaha R3 as well. And against the KTM RC390? Well, let's just say that if I was a betting man, I'm putting my money on Team Green!


Kawasaki Ninja 400 Road Test Review

But if we're nitpicking, we also have to mention the brakes.

Don't get us wrong, braking performance from the 310mm petal front disc and 220mm petal rear disc is excellent.

The Ninja 400 actually brakes from 80kmph to zero in just 28.98 metres, and from 100kmph in 45.50 metres.

Now both of these braking distances are best-in-class. And even ABS calibration, especially for the rear brake, is excellent.

But we really wish that there was more bite in the front brake lever's initial travel.

And no adjustable levers for this expensive a bike feels like a bit of a letdown.


Kawasaki Ninja 400 Road Test Review

It's got surprisingly good ride quality

When it comes to suspension, the Ninja 400 packs beefier 41mm, non-adjustable telescopic forks at the front and a preload adjustable linked monoshock at the back.

The front end is set up a little on the softer side, so on very sharp bumps, it can bottom out.

The rear, on the other hand, feels slightly stiffer in comparison and can feel just a tad bouncy on the same sort of bumps.

But this setup really works well as the front has the pliancy to deal with bad road conditions without knocking the bars out of your hands, while the rear doesn't squat or stand easily under hard acceleration or braking.


Kawasaki Ninja 400 Road Test Review

That makes the overall ride quality not as harsh as the KTM RC390's, or as soft as the Yamaha R3's -- effectively offering what we think is the best-balanced suspension setup in this class.

So whether you're tackling the daily commute or tearing it up on a mountain road, the Ninja 400's suspension really has you covered.


Kawasaki Ninja 400 Road Test Review

Kitna deti hai?

Let's face it, this is a question you're bound to encounter in India no matter what bike you're riding.

The 400 impresses here as well, managing 24.5kmpl in the city and 30.4kmpl on the highway.

For a bike with so much performance, that's really good… bettering some of its competition too!


Kawasaki Ninja 400 Road Test Review

One size doesn't fit all

We've got a bone to pick with the Ninja 400's ergonomics.

At 785mm, the seat height is low enough for most riders, even those who are about 5'5" to 5'6", to get their feet on the ground easily.

The handlebars are kinda tall too, so you don't have to lean too much towards them. And the bars have also been pulled a little towards the rider, so reaching them is easy.


Kawasaki Ninja 400 Road Test Review

Now if you're commuting, this riding position is great. But the moment you want to attack corners -- and this bike just begs you to attack corners -- this riding position feels a bit too tight for moving around on the bike.

Ideally, a slight downward drop of the clip-on bars would've worked much better here.

If you're about 5'8" or under, this might not be much of an issue, but it feels rather cramped if you're a couple of inches taller than that.

And if you're well above 6' in height, the position will feel cramped even when you're cruising on the highway.


Kawasaki Ninja 400 Road Test Review

And speaking of size...

Again we're not exactly complaining here, but where the 300 looks like a scaled down ZX-10R, the 400, with its flatter nose, is more like a mini H2.

The Ninja 400 is available in India in just one paint scheme -- this KRT green, which might seem a little too loud for everyone's taste.

One of the things we did love about the design, though, is the negative LCD instrument cluster which looks rather premium. And the overall build quality is top notch too.


Kawasaki Ninja 400 Road Test Review

But the problem here is that it looks smaller even compared to the Ninja 300.

Now you can blame that on the smaller 14-litre tank and compact ergonomics. So, essentially, those who want a big bike look might want to look elsewhere.


Kawasaki Ninja 400 Road Test Review

The biggest shock

The biggest problem we have with the Ninja 400 is its price.

At Rs 4.69 lakh (ex-showroom India), it's now Rs 1.70 lakh more than the Ninja 300.

Heck, it's Rs 1.2 lakh more than the Yamaha R3.

And you can almost buy two KTM RC390's in the price of one Ninja 400.

If it was Rs 1 lakh cheaper, it would be the perfect machine for anyone upgrading from a 200cc motorcycle.

In fact, at that price, it'd be easy to recommend it to pretty much everyone.


Kawasaki Ninja 400 Road Test Review

And this really breaks our hearts because the Ninja 400 is it is that 'perfect 400cc bike for India' that we enthusiasts have been pining for over the last decade!

It's just too bad most of us who dreamed about a bike like this won't see the sense in spending so much money on it.

Kawasaki Ninja 400/Z400 SuperBike/Supersport Velocity Stacks 2018/2021


Spears Racing have developed new, innovative Kawasaki Ninja 400 Superbike/Supersport Velocity Stack Kit.  This innovative revolutionary design is backed by real dyno testing and our Corbin Custom Design engineering staff.  Our stacks will improve torque/HP and smooth out power delivery.  This allows the rider a truer feel for the throttle which enables more accurate throttle input, improves confidence to get on the throttle sooner and boosts rider confidence.

The OEM Air box of the stock “commuter bike” Ninja 400 contains two different length velocity stacks, one long, one short and two small intake tracks which severely limit the air intake into the engine.  This kit replaces both stacks with our own Spears Racing shorter velocity stacks and instructions to modify your current OEM air box.  These shorter velocity stacks not only allow more air into the engine, but they also smooth out the increased flow of air to really maximize the benefit.

The performance difference with the Spears Racing Kawasaki Ninja 400 Superbike/Supersport Velocity Stack Kit compared to the stock is dramatic.

Here’s a dyno comparison with a stock motor(OEM),stock air box vs stock motor with a MWR filter, Spark exhaust and a power commander five (PCV) vs stock motor with a MWR filter, Spark exhaust and a power commander five (PCV) modified air box (snorkels removed) with Spears Racing’s velocity stacks. You can see the power band carries strong through the complete power and noses over after 11,000 but still increases your max RWHP by almost all the way to red line instead of falling off at 9500 and we don’t lose any important midrange power.

Ninja 400 Superbike/Supersport Velocity Stack kit Facts:

These dyno runs were done with 30PSI in rear tire
This ECU is not flashed or any hidden items to show false readings.
Non Race 89 Octane Fuel (Gas Station)


Dyno proven gains don’t lie! Developed in house on simulation software, the race track and hours on the dyno.

Long Term: Kawasaki Ninja 400 – The Plan

Our Long Term Kawasaki Ninja 400 may have just arrived but we've already got some accessories lined up. An exhaust is high on the list, but first luggage and crash protection!

We’ve now got our Long Term Ninja 400 and we’re building a long list of modifications and accessories that we’re planning on fitting, while you can check out our road test here.

If you haven’t read the road test linked above or the track launch report, Kawasaki’s new Ninja 400 is a great option for new riders. While retaining a competitive price the brand has updated the iconic Ninja with a larger, more powerful and more torquey parallel twin engine, styling is updated, forks are updated, brakes are updated. There’s a whole host of improvements over the outgoing model.

Our Long Term Ninja 400, before mods!

Our Long Term Ninja 400, before mods!

It’s still a flexible, fun and easy to learn on machine, but Kawasaki have really put in the hard yards to ensure it’s still a rewarding machine as you get more experienced. Just like the Ninja 300 was, but better!

We’ll be getting Simon Harris to give us another opinion on the Ninja 400 on the road, to complement his track launch report, plus we’ll be putting together videos on our impressions so far, plus accessory/mod fitment, and the reviews on each, so stay tuned.

First up, our friends at Kenma Australia have set us up with a whole bunch of those great starter mods, including Promoto Oggy Knobbs, a set of Ventura L-brackets for the Ninja 400, and a 36L Wizard Coocase to fit the Ventura rack. Another really smart addition if you’re doing the Ventura luggage is a Promoto Oggy Knobb Fender Eliminator, as it’ll clean up the rear end of your Ninja and shares mounting points, meaning it’s two good jobs to do together.

Here's a look at what we've got so far - Ventura L-Brackets and Coocase 36L Wizard top box, Oggy Knobbs, Promoto Oggy Knobbs Fender Eliminator and some pickup spools to try

We’ll run fitment and reviews on each of these products, but here’s a bit of a look at why we’ve chosen these accessories.

Ninja 400 Crash Protection

The Oggy Knobbs are an ideal option for new riders, if you’ve been looking at buying a LAMS machine you’ll have seen the endless array available second hand which have been thrown down the road on both sides and are in need of plenty cosmetic love.

If you’ve got a new bike you’ll want to protect it as much as possible, and spending a bit on Oggy Knobbs can seriously save you money in the long term. Some of the most common causes of damage for learners is dropping their bike, whether that’s in a carpark, in the wet, or at very low speeds. A bit of crash protection can reduce fairing, case or frame damage and mean repairs are cheap and easy.

There’s no guarantees but if you’ve somehow got comprehensive insurance for your bike without selling a kidney, repairing this kind of your damage yourself will help avoid the black mark on your record and keeping costs down is essential. Also great is that the Oggy Knobbs for the Ninja 400 require no cutting or drilling, they mount through the frame/engine bolts (just requiring fairing removal for fitment) and the plastic pucks are located through a vent in the fairings.

Ninja 400 Luggage

The Ventura luggage is something we swear by here at We’ve got it fitted to many of our own machines and the beauty is that all these systems will fit to any bike with the L-brackets. So if you invest in a Ventura kit for your LAMS bike, you’ll be able to take the rack and bag to your next machine, all you need is new L-brackets to fit the model.

We’ve got the 36L Coocase for the Ninja, which will fit a helmet and be waterproof, making for an ideal commuter option. The case locks onto the bike and is nice and secure, so you could lock your helmet in there when parked and not have to carry it around everywhere you go. There a 30L and 48L option available, but we figured the 36L will suit the Ninja 400 best. We can also put the Sports-Rack and Pack, or Rally-Euro luggage and racks on that we’ve already got.

The whole assembly works off a set of L-brackets. For the Ninja 400 these are a simple installation, they bolt through the rear pillion assembly bolts and a cross member is bolted in via the fender mount bolts. It’s a very minimalist assembly, and if you’re worried about looks a Grab Rail or Sports Rack can be added when storage space isn’t a concern. It’s also a very simple DIY job, with only basic tool requirements. On my Daytona you needed to drill the tail plastics for fitment, but on the Ninja 400 it’s direct fitment, no cutting or drilling required.

Ninja 400 Looks & Cosmetics

The final item on our current list and one that ties into the Ventura install is a Promoto Oggy Knobb Fender Eliminator. These are a very popular option, as standard fenders are large (often heavy), plastic and ugly. It’s made of two anodised elements which bolt together and includes an LED license light. Standard indicators are use and it’s a much cleaner and sexier option than the standard item.

This ties into the Ventura/L-bracket install because you can do the two jobs at once, as the L-bracket requires removing the fender mount bolts.

With the standard indicators used they plug straight in, while the LED license plate light comes with fittings that allow it to be spliced into the original loom with minimal fuss.

Ninja 400 Future Mods

Along with the mods/accessories we’ve already listed, we’ve got a long wish list of things we’d really like to add on this long termer.

The big ticket item is a slip-on exhaust and we’re hoping for an Arrow muffler at this point in time, as they are usually road legal, great quality and not obnoxiously loud. We had one on our last long termer – a Kawasaki Ninja 636 – and it was a great addition. The standard pipe is also pretty ugly, so this is is a bit of a priority.

We’re also organising some pick-up spools so we’ll be able to use a rear stand for cleaning and lubing the rear chain, which is a regular job on a bike that’s getting ridden daily. Adjustable levers and some aftermarket bar-ends are also on the list for a bit of bling.

Our first attempt at pick-up spools was a no-go, with both the sets we thought might fit using M10 bolts, as suited the previous Ninja 300. The Ninja 400 needs M8 bolts.

We’ll also have a look at the Kawasaki Genuine Accessories, with the Radiator Trim (Guard), Seat Cowl in colour matched Lime Green, and Taller Windscreen also looking like good potential options.

If you’ve got any other suggestions, let us know in the comments section and we’ll see what we can do!

We’ll also be doing the first service, with an oil change and new oil filter shortly, alongside a general checkup, so stay tuned for that and the updates on installing the Oggy Knobb and Ventura mods.

Kawasaki Ninja 400 2020 race bike

As already published on our Facebook and Instagram pages we have helped our partner, motorcycle workshop Čarman Motosport from Slovenia, to transform a standard Kawasaki Ninja 400 2020 into a proper race bike for Supersport 300 class. As Čarman Motosport’s blog is in Slovenian language, here’s a list of modifications in English:

  • standard bike: Kawasaki Ninja 400 m.y. 2020
  • Carbonin avio fibre racing kit, customised design
  • bigger cooler for better engine performance, smaller coolant expansion tank
  • racing exhaust system (Akrapovič)
  • slipper clutch
  • quick shifter
  • sport clip-ons (PP Tuning), handlebar protectors (Lightech)
  • race front brake pump (Brembo)
  • braided brakes lines, ABS system removed
  • front brake and clutch lever
  • racing tyres (Dunlop D213 GP Pro)
  • racing suspension (K-Tech)
  • safety wiring on important bolts and nuts (front and rear axle, oil, front sprocket)
  • case savers and crash pads (PP Tuning)
  • central stand attachments
  • adjustable race foot pegs (Lightech)
  • fuel tank cover (PP Tuning), additional hose to empty the fuel tank

Of course all ‘unnecessary’ items like front and back light, blinkers and mirrors were removed. If you’re looking for additional information regarding SSP 300 regulations, you should check PDF file on FIM website: 2020 FIM Superbike, Supersport & Supersport300 World Championships Regulations.

Kawasaki Ninja 400: Same Price, Other Options

From a V-twin powered motorcycle to a budget ADV, here’s everything you can get at the price of the Kawasaki Ninja 400

Now we really like the all-new Kawasaki Ninja 400. It ticks almost all the boxes for a sub-400cc motorcycle barring one. At Rs 4.99 lakh (ex-showroom Delhi), we feel that the Ninja 400 is a tad overpriced for what it offers. That said, if you’re someone looking for a ride in the same price range, here are four motorcycles you’d be better off with.

1) Kawasaki Versys-X 300 (Rs 4.69 lakh)

Ironically, both the least and most expensive motorcycle on our list happens to be a Kawasaki. So let’s start with the more affordable of the two - Versys-X 300. It is the go-anywhere kind of bike you need. Highways? Check. City commutes? Check. Trails? Within reason. The only downside here is that you end up paying over Rs 4.50 lakh for the same engine and underpinnings that you’d find on the Ninja 300, which is Rs 1.71 lakh cheaper! 


2) Benelli TRK 502 (Rs 5.10 lakh)

The Benelli TRK 502 is quite very impressive as it gets components that you’d normally associate with big adventure bikes at a more affordable price point. It looks like a proper adventure tourer and gets a parallel twin engine as well as premium underpinnings. However, in our review, we found the engine to be underpowered and the bike to be a tad to heavy for our liking.

3) Harley-Davidson Street 750 (Rs 5.33 lakh)

How about trading-in the parallel twin of the Ninja 400 for a V-twin? For Rs 30,000 more, you can do just that with Harley-Davidson Street 750. Currently, the most affordable Harley you can buy, the Street 750 offers a bigger capacity engine, comfortable ergonomics and that Revolution-ary V-twin rumble. 


4) Kawasaki Vulcan S (Rs 5.48 lakh)

At just Rs 50,000 more, Kawasaki offers you a more premium and powerful alternative in the form of the Vulcan S. The most affordable member from Kawasaki’s 650cc family, the Vulcan S provides a sense of comfort that one expects from a cruiser. It also grabs eyeballs with its design.
